20080225800 | ACCESS ROUTER AND METHOD OF PROCESSING HANDOVER BY ACCESS ROUTER - An access router including a module buffering first data to be transmitted to a first mobile station, and transmitting the first data to a second access router when the first mobile station moves to the second access router. | 09-18-2008 |
20080298321 | MULTIMODE TERMINAL FOR SUPPORTING FAST HANDOVER BETWEEN HETEROGENEOUS NETWORKS - A multi-mode terminal (MMT) including a plurality of interfaces which provides access capability to heterogeneous networks respectively to provide quick handover between the heterogeneous networks, is provided. In this instance, when a Binding Update (BU) message is transmitted to a home agent via each of the plurality of interfaces, routers existing in a path to the home agent may update path latency information and path bandwidth information as a Binding Unique Identifier (BID) sub-option extension of Mobile Nodes and Multiple Interfaces in Internet Protocol version 6 (MONAMI6). In this case, the home agent may receive the BU message and select a care-of address (CoA) by referring to path latency information and path bandwidth information, included in the BU message. Also, the home agent may transmit a success binding acknowledgement (BAck) message with respect to the BU message of the selected path. | 12-04-2008 |
20090086679 | Apparatus and method for supporting vertical handover on a wireless communication system - A broadband wireless communication system is provided. An apparatus for an information server (IS) comprises an event module for determining whether updating the network information of at least one access network (AN) is needed, a generator module for generating at least one Information_Get_Request packet for requesting the network information of the at least one AN when the updating is needed, a communication module for transmitting at least one Information_Get_Request packet to the at least one AN, and a database (DB) module for storing network information within an Information_Get_Response packet received from the at least one AN. | 04-02-2009 |
20090190524 | APPARATUS FOR DISTRIBUTING DATA TRAFFIC IN HETEROGENEOUS WIRELESS NETWORKS - An apparatus for distributing data traffic in heterogeneous wireless networks is provided. A terminal for transmitting data to a plurality of wireless networks, includes a transmission rule storing unit to store a data transmission rule with respect to the plurality of wireless networks, a data dividing unit to divide first data into a plurality of first data groups based on the stored data transmission rule, a transmission network selecting unit to select an individual transmission network for each divided data group from the plurality of wireless networks based on the determined data transmission rule, and a network access unit to transmit each data group to the selected transmission network. | 07-30-2009 |
20090239534 | APPARATUS AND A SYSTEM FOR REGISTERING PROFILE INFORMATION OF A TERMINAL - An apparatus and system for registering profile information of a terminal in a network is provided. A profile information agent includes a receiver which receives a profile information transmission request message containing profile information associated with a terminal and a transmitter which transmits a profile information registration request message to a profile information server, the profile information registration request message including the profile information. | 09-24-2009 |
20090270102 | MOBILE TERMINAL AND NETWORK DEVICE FOR PROVIDING HANDOVER SERVICE - A mobile terminal and a network device for providing a handover service are provided. A mobile terminal includes a transmission unit to transmit a request message for handover information to a network device, and a receiving unit to receive a response message including the handover information from the network device, wherein the request message and the response message are transceived by an application layer protocol. | 10-29-2009 |
20120113956 | MOBILE COMMUNICATION TERMINAL SUPPORTING MULTI-MODAL COMMUNICATIONS AND METHODS FOR PROVIDING SEAMLESS SERVICE UPON HANDOVER TO THE MOBILE COMMUNICATION TERMINAL - A method of providing a handover service to a mobile communication terminal supporting multi-modal communications, and a mobile communication terminal for performing the method are provided. More particularly, a method of eliminating an interruption of a data transmission service occurring during a handover between different communication networks, and a terminal for performing the method are provided. A method of providing a handover service of a mobile communication terminal supporting multi-modal communications can include: transmitting and receiving data to/from a corresponding node via a first access network and a second access network while simultaneously maintaining an association with the first access network and the second access network, determining a point in time of completing a handover registration, and releasing an association with the first access network after the point in time of completing the handover registration. | 05-10-2012 |
20140204755 | APPARATUS FOR DISTRIBUTING DATA TRAFFIC IN HETEROGENEOUS WIRELESS NETWORKS - An apparatus for distributing data traffic in heterogeneous wireless networks is provided. A terminal for transmitting data to a plurality of wireless networks, includes a transmission rule storing unit to store a data transmission rule with respect to the plurality of wireless networks, a data dividing unit to divide first data into a plurality of first data groups based on the stored data transmission rule, a transmission network selecting unit to select an individual transmission network for each divided data group from the plurality of wireless networks based on the determined data transmission rule, and a network access unit to transmit each data group to the selected transmission network. | 07-24-2014 |
